New stent graft shows promise for clearing long leg artery blockages

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Age ≥ 18 years and of age of legal consent. 2. Women of child bearing potential must have a negative pregnancy test within 7 days prior to the index procedure. 3. Subject has lifestyle limiting claudication or rest pain (Rutherford Becker scale 2-4) with a resting ABI \< 0.9. Resting TBI is utilized only if unable to reliably assess ABI. TBI must be \<0.7. These assessments are required for the target limb, but both limbs are preferred. 4. A superficial femoral artery lesion with \>50% stenosis or occlusion which requires treatment. 5. Stenotic lesion(s) or occluded length within the same vessel (one long or multiple serial lesions) ≥ 120mm to \< 200mm. 6. Reference vessel diameter (RVD) ≥ 5.0mm and ≤ 6.7 mm, angiographically/CTA/MRA defined. 7. Patent popliteal artery 3 cm proximal to tibial plateau 8. At least 1 patent tibial artery to the foot (\<50% stenosis) 9. The target lesion(s) can be successfully crossed with a guide wire and dilated. 10. Poor aortoiliac or common femoral "inflow" (i.e. angiographically defined \>50% stenosis of the iliac or common femoral artery) that would be deemed inadequate to support a successful treatment of the target lesion without prior treatment. Adequate aortoiliac or common femoral "inflow" is defined as \<30% stenosis after either PTA or stenting of the inflow lesion. After treatment of the inflow lesion, the residual pressure gradient across the target lesion will be obtained and if the peak to peak pressure gradient is \< 20mmHg, the subject will be included in the study. 11. A subject with bilateral obstructive SFA disease is eligible for enrollment into the study. The contra-lateral procedure should not be done until at least 30 days after the index procedure (staged); however, if contra-lateral treatment is performed prior to treatment of the target lesion, the waiting period will be at least 30 days prior to the index procedure. 12. The subject is eligible for standard surgical repair, if necessary. 13. A subject who requires a coronary intervention should have it performed at least 30 days prior or 30 days post the treatment of the target lesion. 14. Subject must provide written informed consent. 15. Subject must be willing to comply with the specified follow-up evaluation schedule. Exclusion Criteria: 1. Age greater than 90 2. Thrombophlebitis or deep venous thrombus, within the previous 30 days. 3. Receiving dialysis or immunosuppressant therapy within the previous 30 days. 4. Thrombolysis of the target vessel within 72 hours prior to the index procedure, where complete resolution of the thrombus was not achieved. 5. Stroke within the previous 90 days. 6. Ipsilateral femoral aneurysm or aneurysm in the SFA or popliteal artery. 7. Required stent placement via a popliteal approach. 8. Procedures which are pre-determined to require stent-in-stent placement to obtain patency, such as in-stent restenosis. 9. Significant vessel tortuosity or other parameters prohibiting access to the lesion or 90° tortuosity which would prevent delivery of the stent device. 10. Required stent placement within 1 cm of a previously deployed stent. 11. Known allergies to any of the following: aspirin and clopidogrel bisulfate (Plavix®), ticlopidine (Ticlid ®),and prasugrel (Effient®); heparin; Nitinol (nickel titanium); or contrast agent, that cannot be medically managed. 12. Presence of thrombus prior to crossing the lesion. 13. Known or suspected active infection at the time of the procedure. 14. Use of cryoplasty, laser, or atherectomy devices in the target vessel at the time of index procedure. 15. Restenotic lesion that had previously been treated by atherectomy, laser or cryoplasty within 3 months of the index procedure. 16. History of neutropenia, coagulopathy, or thrombocytopenia that was unexplained or is considered to be at risk for reoccurrence. 17. Known bleeding or hypercoagulability disorder or significant anemia (Hb\<8.0) that cannot be corrected. 18. Subject has the following laboratory values: a. platelet count less than 80,000/μL, b. international normalized ratio (INR) greater than 1.5, c. serum creatinine level greater than 2.0 mg/dL. 19. Subject requires general anesthesia for the procedure. 20. Major distal amputation (above the transmetatarsal) in the study or non-study limb. 21. Patient has had a revascularization procedure on the target limb within 30 days of the planned index procedure 22. Patient has a planned amputation of the target limb 23. Previous bypass surgery on the target limb 24. Subject is pregnant or plans to become pregnant during the study. 25. Subject has a co-morbid illness that may result in a life expectancy of less than 1 year. 26. Subject is participating in an investigational study of a new drug, biologic or device at the time of study screening other than a PQ Bypass study. NOTE: Subjects who are participating in the long term follow-up phase of a previously investigational and now CE marked product are not excluded by this criterion.
